Title: Vibration control device
Inventor: GOMI SHOJI
IPC: F16F15/126
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of stress concentration on a specific part of an elastic body so as to prevent the generation of early cracking by setting a filling port at the time of vulcanization-molding the elastic body, into a position near an outer member or an inner member. SOLUTION: A protrusion 5 formed at a filling port of molding material of an elastic body 3 is formed in a position near an outer member 1, that is, the filling port at the time of vulcanization-molding the elastic body 3 is so set as to be formed near the outer member 1. At least one edge part of both edges of the inner peripheral surface of the outer member 1, and its adjacent part are cut in the direction of enlarging an inner diameter to set the filling port of the elastic body 3 on the cutout peripheral surface 1A. Stress concentration is not therefore generated near the root of the protrusion formed in the place of the filling port so as to be able to prevent the generation of early cracking.

Title: Method forming color signal in pal system by digital processing
Inventor: GENTOU KATSUNORI
IPC: H04N9/64
Filed: 1987-12-10
Abstract: PURPOSE:To generate a highly stable color signal with no adjustment while simplifying structure by generating a digital signal in chrominance subcarrier frequency fSC by a single frequency locked to a horizontal scanning frequency fH, separating the signal into (R-Y), (B-Y) signals, shifting them by phase addition or the like and extracting them while being converted into an analog signal. CONSTITUTION:A crystal oscillator 1 frequency 17.625MHz synchronized with the horizontal scanning frequency fH to generate a digital sampling clock. An R-Y, B-Y generator 7 separates a signal SC (sawtooth wave) generated by a chrominance subcarrier frequency fSC generator 4 into R-Y, B-Y. The phase shift in the sawtooth wave state is implemented by having only to add values simply. Waveform synthesizers 11, 12 use the R-, B-Y so as to control the level of the continuous sinusoidal wave to apply modulation. Then a delay circuit 13 uses the R-Y, B-Y to apply correction of repetitive time. An adder 14 adds the modulated R-Y, B-Y to convert the result into a chrominance signal and an adder 15 adds the chrominance signal to the retarded Y signal to form a video signal.
